Do all objects have a momentum?
No. An object has momentum only if it is in motion..There are two kinds of momentum: linear momentum(or translational momentum), and angular momentum (or rotational momentum)..Linear momentum is a vector quantity and is calculated as mass x velocity (p = mv). Therefore, if an object's velocity is zero, then it has no linear momentum, but if an object is in motion, then it does have linear momentum..VERY IMPORTANT NOTE: Velocity, and therefore linear momentum, is always relative to the frame of reference. For a more complete discussion about velocity, see the related answer, referenced below, entitled 'How to Find Velocity'..Angular momentum is a pseudovector quantity that describes the momentum of an object that is spinning or rotating in place. An object has angular momentum only when it is spinning, or rotating about an axis. When an object is not spinning or rotating, then it does not have angular momentum..It is possible for an object to have only linear momentum, only angular momentum, or both angular and linear momentum. Note that this discussion falls apart in quantum mechanics, so we are only discussing classical physics - that is, every day observable objects, and not light particles (photons), electrons, or other quantum particles..All objects do have inertia, which is a resistance to a change in its momentum.
An object that has linear momentum must also have?
Momentum. The formula for kinetic energy is: KE = .5 * m *v^2 The formula for momentum is: p = m * v If an object has kinetic energy, then both mass and velocity are non-zero, which implies that the momentum is also non-zero.
Relation between angular velocity and linear velocity?
Both have mileage.
What is the property of a moving object that depends on the objects mass and velocity?
It can be either linear momentum or kinetic energy since they both are associated with mass and velocity.
What is one way to increase the momentum of an object?
Momentum is of two kind. One is linear momentum and the other is angular momentum. Linear momentum is defined as the product of the mass and the velocity. Hence a vector quantity. To change the momentum of a given body with its mass constant, its velocity is to be changed. Velocity change could be made by changing its magnitude or direction or both. Angular momentum is the product of moment of inertial and the angular velocity. Same manner, angular momentum is also a vector quantity as angular velocity is a vector quantity. Most of us think that moment of inertia of a body about any prescribed axis is also a vector quantity. It is totally wrong as far as my approach is concerned. Moment of inertia is a scalar quantity. So to change the momentum, some force can be applied by allowing a moving body to collide with. Angular momentum can be changed by applying torque on it. Torque colloquially saying is a turning force. Moment of effective force about an axis is termed as torque.
Two ways angular momentum and linear momentum are alike?
They both have momentum and their equations are similar.

Why is angular momentum used?
In the same way that objects in linear motion tend to remain that way, objects which are rotating tend to keep rotating. Thus, we need both linear and angular (rotational) motion.
An object that has linear momentum must also have?
Momentum. The formula for kinetic energy is: KE = .5 * m *v^2 The formula for momentum is: p = m * v If an object has kinetic energy, then both mass and velocity are non-zero, which implies that the momentum is also non-zero.

Why does the concept of Bohr orbits violate the uncertainty principle?
The Bohr Model of a single-electron atom assumes that the energy levels of electron orbits are fixed due to the quantization of angular momentum of the electron while in orbit. The problem occurs because angular momentum depends on both the radius of the orbit and the velocity of the electron in that orbit. If one or the other is uncertain, then it is impossible to know the angular momentum. Heisenberg showed that either one or the other MUST be uncertain. If we are certain about the radius, we MUST have uncertainty about the velocity -- and vice-versa. Thus, angular momentum of an orbting electron can NOT be quantized, because it can not be known.
If a trapeze artist rotates twice each second while sailing through the air and contracts to reduce her rotational inertia to three-fourths how many rotations per second will result?
Well, the only thing you really have to do is take how many times she rotates before the reduction in the distribution of mass and times it by the reciprocal of the fraction they give you. So, just take 2 times 4/3 and you get 2.67 rps.

How is a tornado in a bottle project similar to a real tornado?
Both the tornado in bottle and a real tornado involve a vortex that strengthens via the principle of conservation of angular momentum.

It can be either linear momentum or kinetic energy since they both are associated with mass and velocity.
Why do toilets swirl?
Toilet water swirls due to a law of motion called "Angular Momentum". This is one of the laws of planetary motion discovered by Keppler. It basically describes the natural movement of matter whether it be water in a toilet bowl, planets around a sun or galaxies around a black hole. This natural movement is of a circular nature.Of course in a toilet bowl often times the water shoots out at an angle upon flushing so that a circular motion is created on purpose. But a more natural example of this is the water that goes down the drain in a bath tub. Again we see the same motion as a galaxy around a central mass in the center. This is theorized to either be a black hole or simply a globular cluster of stars forming a gravitic mass at the center of each galaxy to which other stars are pulled into via the strong gravitational pull of this gravitic mass or black hole.For a much more detailed and specific explanation of angular momentum, keep reading and visit the Wiki link below.In physics, the angular momentum of a particle about an origin is a vector quantity equal to the mass of the particle multiplied by the cross product of the position vector of the particle with its velocity vector.[1] The angular momentum of a system of particles is the sum of that of the particles within it.[2] Angular momentum is an important concept in both physics and engineering, with numerous applications. Angular momentum is important in physics because it is a conserved quantity: a system's angular momentum stays constant unless an external torque acts on it. Rotational symmetry of space is related to the conservation of angular momentum as an example of Noether's theorem. The conservation of angular momentum explains many phenomena in nature. http://en.wikipedia.org/wiki/Angular_momentum
